FeNi nanoparticle deposition on a W(110) surface — •Matthias Werner, Hendrik Bettermann, and Mathias Getzlaff — Institute of Applied Physics, University of Duesseldorf
By a continuously working arc cluster ion source (ACIS), nanoparticles consisting of Fe and Ni with equal amount are prepared and deposited under UHV and soft-landing conditions on a W(110) surface. The composition is defined by the alloy of the anode in the cluster source, in our case it is Fe50Ni50. Using this preparation procedure the nanoparticles are charged which allows a mass separation by an electrostatic field unit. Our experimental setup enables us to generate particles with diameters from 4 nm to about 15 nm. Size and shape of the deposited nanoparticles are determined by STM as these properties are expected to be mainly responsible for their electronic and magnetic behaviour.
